DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now by reference characters to the drawings which illustrate the preferred embodiment of the present invention, A generally designates a flexible package comprising an outer envelope 1 having end edges 2, 3, side edges 4, 5 with intervening side panels 6, 7. Envelope 1 is formed from a single web of laminated sheet material incorporating a thermoplastic, heat sealable film layer 8, such as polyethylene, pliofilm, polycarbonate, polypropylene, or the like, and a moisture and gas impervious layer 9, such as aluminum foil. Said web is folded back upon itself at end edge 2 with film layer 8 being on the inside whereupon end edges 3 and side edges 4,5 are heat sealed, as at 3 4' and 5' respectively; said side panels 6,7 cooperating with seals 3', 4' 5 and end edge 2 to define a chamber 10.

Disposed within chamber 10 is a pouch 11 having an end edge 12 and a pair of side edges 13,14, there being an opening 15 at the opposite end edge. Said pouch 11 is formed from a web of laminated sheet material incorporating a thermoplastic, heat sealable film layer 16, of similar construction as layer 8 of envelope 1 and a moisture-absorptive layer 17, such as fabric or the like. The web of said pouch 11 is folded back upon itself at end edge 12 with film layer 16 being on the inside whereupon side edges 13,14 are heat sealed, as at 13, 14 are heat sealed, as at 13', 14', respectively.

Said pouch 11 is attached to envelope I adjacent opening 15 by aligned heat seal lines 18,18 which extend transversely across the respective side panels 6, 7 joining film layer 8 of envelope 1 to fabric layer 17 of pouch 11 for effecting a common bond therebetween. In heat sealing lines 18, 18' the temperature, pressure and time factors of the sealing operation must be such that film layer 16 of pouch 11, adjacent pouch opening 15, will not be sealed for closing opening 15. This can be accomplished by utilizing a lower density film for layer 8 than film layer 16, as a lower density film will seal at a lower temperature.

Presented within envelope 1 substantially around the perimeter thereof is a tear string preferably constructed of nylon material, although not limited to such, which may be stitched into place or held in position by said heat seals 3, 4, 5; one terminal portion 20 of same being also held between seal lines 18,18, Spacedly from end edge 3, outer envelope 1 is provided with a transversely disposed tear line 21 for defining a tear flap 22 which contains a portion of tear string 19. Said tear line 21 is longitudinally spaced from and in parallel relationship to said seal lines 18,18 so that upon severing flap 22 from envelope 1 ready access to the interior of pouch II is provided.

The moisture absorptive fabric layer 17 of pouch 11 may contain a treatment agent of known types depending on the desired use of package A. In such instances the common bond seal 18 serves as moisture barrier for preventing moisture from seeping into the interior of pouch 11. Said package A may also be provided with a thin line transverse seal 23 which bonds film layer 8 to film layer 17 for preventing moisture of the treatment agent from receding beyond same. In the latter instance, the treatment agent is applied to the fabric layer 17 in the region between said thin line seal 23 and end edge 12 for maintaining a portion of the fabric layer 17 in a dry state.

It will be understood that although the envelope 1 and pouch 11 have been described as being formed of a single web of laminated material, that the same may be easily constructed from two webs in a four-side seal or in a vertically made. pillow-type pouch without departing from the principle of the present invention. Additionally, although thermosealing has been defined as the preferred method of sealing the respective envelope and pouch, it is obvious that other means, such as gluing, adhesive bonding, etc., or any combinations thereof, may be readily utilized.

In operation, a user will pull tear flap 22 along tear line 21 for effecting transverse opening of envelope 1 adjacent end edge 3, thereby providing access to opening of pouch 1 l, as shown if FIG. 3. The user will then insert a finger f into opening 15, grip package A between said finger f and his thumb r and thence continue to sever edges 5, 2, and 4 of envelope 1 by pulling on tear string 19, as shown if FIG. 4, until terminal portion is reached. It will be noted that tear string 19 may remain attached at its terminal portion 20 to package A through its engagement between seal lines 18,18 or may be readily disengaged therefrom upon further pulling action. The user will then peel side panels 6, 7 rearwardly toward his wrist for exposing fabric layer 17 and grasp panels 6,7 with thumb t and the remaining fingers as shown in FIG. 5. It will thus be seen that side panels 6,7 of envelope 1 become an extension, as at 24, of pouch 11 for permitting a firm, secure grip upon same during manipulation of package A without having to touch the fabric layer 17.

In the preferred form of flexible package A, a dentifrice is deposited upon fabric layer 17 and the tear string 19 is comprised of nylon dental floss. Upon the opening of envelope 1 in the manner described above, the dental floss tear string 19 may be utilized for dislodging food particles from between the teeth after which fabric layer 17 is utilized for vigorously rubbing the teeth surface for removing food debris and plaque. The dentifrice used may be any conventional teeth cleaning and deodorizing agent. It will be observed that after package A has been utilized it may readily by disposed of in a common waste receptacle.

Referring now to FIG. 8 of the drawings, it will be seen that flexible package A may be constructed so that a user may insert his entire hand within pouch 11, and if desired, may tie tear string 19 around his wrist or forearm, as at 25, for maintaining package A against undesired movement. In addition, the extension 24 of pouch 11 can be fully extended up the forearm and held securely by the tear string 19 or by other means to achieve a maximum protected area. In this form, package A may be utilized as a medical dressing for cleaning wounds, for removing cosmetics, or for washing ones face, as well as for countless other practical uses. A treatment agent may be deposited on fabric layer 17, such as an antiseptic agent, a cleaning solution, or the like.
